Why do you say it will not work with L7?
The amplifier is digital, but the signal that arrives at the source is analog and is the same (Professional) is HIFI, is L7???
Will lose the DSP effects, but the rest??

Your own question and answer are absurd. What about searching to clarify your own misinformation?

The unit looks pretty good. I'm looking forward to your DIY install, I was really considering buying one of these but the thought of paying 1k+ for a shop to install it on top of the price of the unit really was deterring me. GL

I bet that the shop that quoted you $1000 for install thought that your 3-Series was an E46 and not an E90, and that the Nav that you will install was a double DIN.

There are many threads on this but L7 is optical and would require a lot of modification.

Wait so this setup doesn't work with Logic7? What exactly does that mean? The sound quality won't be good as the OEM system?

It means that if you have a logic 7 system you cannot put this in without bypassing the logic 7 amplifier and either running all new speaker wires or a new external amplifier. Correct me if i am wrong Technic. Its the same as adding any other aftermarket headunit and there are a ton of threads on them and Logic7.

Hmmm....looks nice. If someone with a base unit in a 2010 or pre 9/10 build 2011 installs this it appears as though they should get a better sounding system as well, at least it will be better suited to adding an amp. Maybe technic can chime in on this, but the signal this is putting out should be a flat curve and if the built in amp is 50x4 it would probably be an upgrade over the non external amped system. And if the curve is flat, it would be set up perfect for adding a four channel amp....

Sounds about right, any headunit upgrade is usually better than OEM, especially with a vehicle that is standard audio as it will push more power to the stock speakers. Also the RCA's make it very easy for an amplifier like you stated, and includes easy remote wire tapping.

I'm watching carefully your thread cause as of today i'm also the owner of a
Dynavin E9X which i'm planning to install it to my 335i.
I'm gonna go the DIY way so i'll post some pics on your thread if you don't mind in case you want to use them on your thread.

Here are a few of what i received today.

The Main Unit

The DVB-T Tuner in which i'd like to ask wether i should install both Antennas that it came with and what is the USB port for in the back of the tuner ??

Back Side

The Main Wires, the remote control and a USB Extension Cable.

And the Bluetooth Mic, the Steering wheel buttons IR box, the IPOD cable, the GPS Antenna and 2 more USB Extensions.

Any suggestions of where to place the GPS Antenna and the 2 TV Antennas are VERY Welcomed. (As also about the USB, AV, and IPOD cables)

It could be possible that this unit slot for the automatic climate control can be modified in a way that the manual A/C trim (#2) can be installed:

Well the unit is obviously molded for the Auto AC so im sure it can be done but not without a good amount of effort and skill. I would assume that the auto and manual are the same size? That could be a reason if they arent.

Also Sergio,
Feel free to keep posting, i will make a DIY and such and we can compare and make sure all bases are covered!
